Knowing the method of refining the rune bone spirit sword, Chen Xun finally understood why Gu Yuzhang and the others chased and killed the demon python, why they had to take the Liangyi Xuantian coil on their bodies.

Chaos demonization turned into Chaos Xuantian, refining the demon python with the calamity wind and fire, the demon python primordial god was forced to retreat into the rune bone, Chen Xun took the opportunity to seal his primordial spirit in the rune bone, and then he could calmly refine the essence of the scales, flesh, muscles and bones left after the demon python was smelted by the calamity wind and fire, little by little into the rune bone.

After removing a large amount of residue, the rune bone sword that was finally refined can be said to be a special-shaped giant sword, with a whole body as red as blood, the blade of the sword stabbing back like a sharp cold snake tooth, and swallowing like a hideous python.

The head and tail of the alien giant sword were close to eight feet, two feet longer than Chen Xun's entire person, and the whole body was like a demon python full of backspines that was pressed into a sword shape by infinite huge force.

"You should always know how deeply you offended the female demon of the Heavenly Dao Sect Xu Zhaorong this time, right?" The Chaos Demon Transformation could not leave the ten zhang range of the Demon Detention Banner, which was quite gloating.

The wild tribes of Snow Dragon Mountain all have a secret method of refining demon beast rune bones into magic weapons.

In fact, Chen Xun also planned to try to refine the Eight Desolation Xuanyuan Pagoda on the basis of the Black Viper King Python Rune Bone obtained before, but if he wanted to refine a superb Heavenly Rank magic weapon, it was a huge project, even if Kui Long Pavilion did its best, it would take several years or even more than ten years to succeed.

And with the help of the Chaos Demon, it only took him more than ten days to refine the rune bone sword roughly, and this speed was indeed too terrifying.

Under the refining of the calamity wind and fire, the demon python rune bone seemed to be born in the shape of a sawtooth giant sword in front of him, and there was no need for Chen Xun to control it.

The collapse of heaven and earth is a disaster, wind and fire, and heaven and earth all return to the original and original ......

Calamity is different from any Celestial Flame, but it is no weaker than any Celestial Flame.

The value of the Chaos Demon Yuan Fetus is actually much higher than the value of the Liangyi Xuantian Disk itself.

Now the Heavenly Dao Sect thinks that the Chaos Demon Yuan Fetus has been strangled by him, so he can only take the Liangyi Xuantian Disk with hatred, if the Heavenly Dao Sect knows that the Chaos Demon Yuan Fetus is actually accused by him, how will it react?

"Xu Zhaorong has not cultivated into the Yuan Fetus, why does it seem that she is more difficult than her brother Xu Zhilong?"

"If it weren't for the fact that she had been shattered in two battles with people, she would have far surpassed her brother in cultivation," the Chaos Demon said gloatingly, "Even so, she still has the qualifications to fight for the first true inheritance of the Heavenly Dao Sect, and her combat power is not under the ordinary Nirvana Realm Xuan Xiu." ”

"What powerful magic weapon does she have, or what powerful Xuangong Dao method does she cultivate?" Chen Xun asked.

"I was captured by his father Xu Zheng, and I was forced to plant a secret oath in the depths of the Yuan womb, and my words and deeds must not endanger the lives of the children of the Xu family - what is so powerful about Xu Zhaorong, you will know when you meet her. The Chaos Demon was silent.

Xu Zheng is the sect master of the Heavenly Dao Sect Jin Xifeng, he has already passed the seven tribulations after entering the Nirvana Realm, except for the immortals of the Brahma Realm who are hidden in the world, he is one of the few Heavenly List powerhouses in Tianjun who dares to enter the Chaos Heaven Domain, and his cultivation is so deep that it is difficult to guess at all.

The secret oath that Xu Zheng planted in the depths of the Chaos Demon Primal Fetus may only be a wisp of divine thought, unless Chen Xun completely shatters and melts the Chaos Demon Primal Fetus, otherwise even if he uses Xuanyin True Water, he will not be able to wash away Xu Zheng's wisp of divine thought.

And by smashing and melting the Chaos Demon Primal Fetus, the Chaos Demon will no longer be a Chaos Demon.

A strong man like Xu Zheng would not be born even if he was light, Chen Xun thought to himself that the greatest threat to him in the future of the Heavenly Dao Sect was Xu Zhaorong, who was qualified to fight for the first true disciple of the Heavenly Dao Sect.

In the Heavenly Dao Sect, which has been inherited for millions of years, the sect has the old monsters of the Brahma Realm in charge, and the true monarchs of the Nirvana Realm do not know how many mortals, no matter what the cultivation realm is, as the first true disciple of the heir of the sect, the strength is bound to be so strong that it is against the sky, maybe there are more than one or two Dao magic weapons.

Not to mention the Heavenly Dao Sect, a powerful sect that is among the ten sects of the Western Continent, what the true disciples are cultivating must be the Nine Tribulations Refining Body and the Shattered Star Fist, which are immortal supernatural powers, maybe they have already cultivated all kinds of supreme golden bodies.

Chen Xun was confident that his Divine Soul cultivation and the various Divine Passage Methods he had cultivated would not be similar to the True Transmission disciples of the Heavenly Dao Sect, but he did not have a strong Dao weapon by his side, and he wanted to compete with the Ten True Legends of the Heavenly Dao Sect this time, but he was still extremely reluctant.

Although Chen Xun obtained the third-order Dao Treasure Xuanjiang Seal from Longshan, he had not been able to completely refine it at this time, and the Blood Crow had not been able to completely melt the immortal fetal Dao species in the Xuanjiang Seal retained by the Beidou Immortals, so Chen Xun could only leave the Xuanjiang Seal in the Yi Clan's Secret Palace.

This is also just in case, if he unfortunately dies in the Tianjun World, he may also be reincarnated through the blood crow.

This is a way out left for him by the Qingniu Master.

Chen Xun didn't think about what he had or didn't have, and included all the Heavenly Detention Demon Flags in the Little Sumeru Ring.

"You're crossing the river and demolishing the bridge!" The Chaos Demon God Idea can still come out of the Little Sumeru Ring, it thought that if it helped Chen Xun refine into a rune bone sword, the treatment would be slightly improved, but he didn't expect Chen Xun to put it into the Little Sumeru Ring along with the Demon Flag for the first time, "You let me take a few more sips of Hongmeng Yuan Breath at this time, and when I meet Xu Zhaorong, I can at least help you save your life......"

"I thought you didn't know that the Void Yuan Bead could give birth to Hongmeng Yuanxi. Chen Xun pouted and smiled.

"Heaven and earth are destroyed in chaos, born in chaos, how can I not know Hongmeng Yuanxi, old demon?" screamed the Chaos Demon.

"Do you recognize the mirage dragon bones hidden under the Void Yuan Spirit Land?" asked Chen Xun.

Chen Xun asked, and the Chaos Demon stopped talking.

Chen Xun smiled coldly, the Chaos Demon seemed to help him, but he was extremely scheming, where would he dare to let the Chaos Demon have a chance to regain his cultivation at this time?

Chen Xun walked out of the Xuyuan Pearl, and saw that the glazed treasure ship had already left Yongming Island, and the wind and rain outside the porthole were like darkness, thunder and lightning, and the nuclear boat treasure ship that Wang Chong, Wang Teng, Jiang Wei and others were riding followed more than ten miles away.

"What kind of sword is this, how can a demonic aura come out?" Black Tea looked at the red-blooded giant sword in Chen Xun's hand and asked suspiciously.

"The Red Blood Snake Sword!" Chen Xun said, "It's still a rough billet, and it needs to be tempered well before it can be of great use." Is there anything unusual on board?"

"Heading towards the sea ruins, in the past ten days, Wang Qingchang, Nangong Xun, Zhao Daolin and others have been diving in the cabin to ......," Black Tea said.

"Then there will be a while until the sea ruins......"

Chen Xun took out a small tripod filled with Xuanchen sand.

He left the Blue Lotus Treasure Lantern to Qing Xuan for self-defense, and he turned the Xuanyang True Yuan into the Blue Lotus Flame, and then gradually increased to the Red Lotus Flame and the Glass Flame The speed became extremely slow.

Don't fight with the enemy, just use the glazed flame to refine the Xuanchen sword qi from the Xuanchen sand, and the speed is slow.

Chen Xun integrated the Xuanchen sword qi refined from the Xuanchen sand into the red-blooded snake sword little by little, and saw that the blood color of the sword body became clearer and clearer, as if there was a feeling that infinite python blood was about to erupt out.

Even if there was enough glazed flames, the speed of refining and gathering Xuanchen sword qi was still too slow, and Chen Xun estimated that the Xuanchen sword qi that the Red Blood Snake Sword could integrate would take about three or five years to refine.

In about half a month, he will arrive at the periphery of the sea ruins, and Chen Xun will not have three or five years to strengthen the red-blooded snake sword in his hand.

Chen Xun spit out the Xuanchen sword qi he had refined in his early years from the veins of the hundred bones.

This part of Xuanchen's sword qi, Chen Xun has practiced for more than twenty years, and every subtle sword qi is integrated into his divine soul aura, which can change the sword shape at will, and can also adapt to a qiē sword technique.

On the basis of Xuanchen's sword qi, he condensed the Yuan Force of Heaven and Earth with the Great Freedom Sword Technique, and molded it into a Law Phase Golden Scale Sword, which could increase its power several times.

Unless the Great Freedom Sword Technique can be integrated into the Little Thousand Sword Formation Technique, and reach the realm of absorbing the Yuan Force of Heaven and Earth in the Sword Array, the consumption of the Imperial Envoy Xiao Thousand Sword Formation is extremely great, and the True Yuan Mana in Chen Xun's body can be exhausted in a few moments, and Chen Xun can only use the Law Phase Golden Scale Sword to resist the enemy at this time.

Chen Xun was also worried that if this Xuanchen Sword Qi was integrated into the Red Blood Snake Sword, if he couldn't achieve the corresponding effect, his strength would not only increase, but even weaken significantly.

After thinking about it again, Chen Xun felt that it was still worth trying.

Before his death, the demon python had many magical powers such as absorbing the Xuan Ming evil qi, storing the evil element, and releasing the Xuan Ming Thunder, and the red-blooded dark snake sword refined by the essence of the demon python's flesh and blood and the original god, these many magical powers will only be stronger.

In addition to not being able to directly connect with the Heaven and Earth Yuan Force, the Red Blood Dark Snake Sword was no weaker than the Law Phase Golden Scale Sword condensed by the Great Freedom Sword Intent, and the Red Blood Dark Snake Sword Sword was combined into the Small Thousand Sword Formation and the Suppression Sword Array Formation, in addition to multiplying the power of the Thunder Sword Light and the Thunder Sound Sword Demon, it could also deduce many magical powers.

Chen Xun couldn't sacrifice the Dutian Detention Demon Banner lightly, and the Shattered Star Fist he cultivated was incomplete, and the sword momentum plus the nine potentials of the stacked waves was the main basis for him to win against the enemy at this time.

A superb Heavenly Weapon Spirit Sword with a Weapon Spirit was what he needed most at this time.

Thinking about this, Chen Xun no longer hesitated, and it took more than ten days to completely integrate this part of Xuanchen's sword qi into the Red Blood Dark Snake Sword.

Because of this part of Xuanchen's sword qi, he had been cultivating for twenty years, and as Xuanchen's sword qi merged into the Red Blood Snake Sword, his divine soul aura penetrated into every subtlety of the sword body.

At this time, he solved the demon python's primordial god seal, and completely suppressed the demon python's primordial god only by revealing the sword body.

That's not enough.

When fighting against the enemy, he wants the Demon Python Yuan God to become the instrument spirit that controls the Red Blood Snake Sword, and he needs to completely refine the Demon Python Yuan God's will to resist.

And at this point, he will use the Xuanyin True Water to refine the Demon Python Yuan Shen, and he will not be afraid of it at all.

Unconsciously, more than ten days passed, and Chen Xun refined a drop of life essence blood into the demon python primordial god, and the red blood snake sword was completely refined.

Even if the innate formation prohibition inside the Red Blood Snake Sword was still possible, it was still possible to further improve it, and it was far beyond Chen Xun's ability at this time.

"What a strong magic sword!" The black tea body is a demon body, but it is also shocked by the monstrous aura exuded by the Red Blood Snake Sword, "I'm afraid that the Dao weapon is only of such a level, right?"

"It's still a little way to reach the level of the Dao weapon, not only is it infinitely ......close," Chen Xun said, the ordinary refining weapon sect, refining the magic weapon with the demon beast rune bone, will more or less damage part of the formation prohibition, and with the assistance of the Chaos Demon, the innate formation prohibition in the demon python rune bone has not been damaged, but even improved, but after all, it still can't reach the level of the Dao weapon.

Sensing that Wang Qingchang, Mrs. Tianyin and others all walked out of their respective cabins and concentrated on the top cabin deck, Chen Xun also walked on the deck with black tea, and saw hundreds of miles ahead, the streamer was shining, and the space seemed to be twisting and turning, and asked Wang Qingchang: "Even if you enter the sea ruins in front?"
